Such a fascinating dream, @Maggi! 
I wonder if it was influenced by the current Mercury Retrograde- others (and myself included!) have been having some strange dreams lately.
Francisco gave a wonderful interpretation of the dream- I love the message he revealed for you!
Just adding on to that- I’ve found that the best way to measure the meaning of the dream is to examine how you feel as you experience it. That warm and happy feeling you mentioned is a clear pointer that the overall message is one of positivity and success 
.
Other meanings and revelations about the dream may reveal themselves with time- so consider keeping a Dream Journal and writing both the dream and your interpretation of it. Then in the future, you can look back and reflect on what the dream led to! 
Blessed be!
